Trap of Feature Diversity in the Learning of MLPs

no code implementations2 Dec 2021 Dongrui Liu, Shaobo Wang, Jie Ren, Kangrui Wang, Sheng Yin, Quanshi Zhang

We explain such a two-phase phenomenon in terms of the learning dynamics of the MLP.

Interpreting Representation Quality of DNNs for 3D Point Cloud Processing

no code implementations NeurIPS 2021 Wen Shen, Qihan Ren, Dongrui Liu, Quanshi Zhang

In this paper, we evaluate the quality of knowledge representations encoded in deep neural networks (DNNs) for 3D point cloud processing.


Deep Models with Fusion Strategies for MVP Point Cloud Registration

1 code implementation18 Oct 2021 Lifa Zhu, Changwei Lin, Dongrui Liu, Xin Li, Francisco Gómez-Fernández

The main goal of point cloud registration in Multi-View Partial (MVP) Challenge 2021 is to estimate a rigid transformation to align a point cloud pair.
